Question

If the __________ is damaged, a person can form visual memories but not verbal memories.​

Answer 1

Rathus explained in a situation that an Air Force cadet had a thalamus damage after a fencing activity. After the accident, he can no longer have verbal memories but only visual memories.

The thalamus is a part of the brain responsible for connecting both motor and sensory messages to the cerebral cortex. It is also responsible for creating verbal memories.

Answer 2

If the thalamus is damaged of a person, then they can only form visual memories but not verbal memories.

Further Explanation:

The structure of a thalamus is a midline symmetrical of two halves. It is present in the brain of a vertebrate. They are present in between the cerebral cortex and midbrain. The thalamus is a part of diencephalon which in turn is a part of the forebrain. The main functions of a thalamus are:

• Pass motor and sensory signals to cerebral cortex
• Regulation of sleep, alertness and consciousness
• Major product of the embryonic diencephalon
• Responsible for learning and memory

The inputs from the receptors are received by the nuclei present in the thalamus. The sensory information is processed by it and then the information is transfer to the cerebral cortex. In this way, it acts as a gateway for the sensory impulses it receives from the various receptors. Thus, if a thalamus of an individual is damaged, then they can only make visual memories. They cannot make verbal memories.
